> They've offered $10k, which is not a life changing amount of money for me. This seems too low to me, although without more details about your side project and how much revenue it generates, I can't say this very confidently. > I suspect that rejecting this offer may eventually lead to a termination of my employment. How much are you earning from your job in the first place, versus the amount you earn from this software? I think there are a few possibilities: you can counter with a higher number if you like the company you work for, or you can counter for the same number plus a significant equity stake in the company, so that you retain some upside. If you want to get creative, you could even sell them a license to use your software along with source code access, but keep selling to third party companies yourself. If you don't really want to sell it in the first place, then don't. I think a $10k is wayyyy too low to force a sale unless your software is trivial to replicate.
